.To all whom t may concern.-

Be it known that I, RICHARD C. HrLLs,'a sub `ect of the King of Great Britain, residing t e city andcounty of Denver and Stateof Colorado, have invented certain new'and useful Improvements in'Revolving Driers; and I do declare the following to be a full, clear, and exact description ofthe invention, such as Will enable others skilled in the art-to same, reference being had tothe accompanying drawings, vand to the letters of reference I .l marked thereon, which form: apart of this specification.

en relates to improvementsin My inventi revo vingdriers adapted for use in treating briquet material preparatory to passing ,the material to the briqueting machine or press where. the briquets are manufactured.l This is one of a number rof machines through which themateiial is assed during the preparatory stage and ta es the material from the .mixing-scrubber covered -by anap lication filed by me July 3, 1905, Seria No. 268,259.

The construction consists, generally speaking, of inner and outer concentric cylinders -connected to rotate in unison. The outer cylinder in constructions of this class is usually 'termed a mantle and the heat necessary in the treatment .of the material passing throu ated, preferab h the inner cylinder is generthrough the instrumentality of as-burners, which deliver the necessary fue -gas for vpurposes of combustion at one end of the revolving structure and into the space between the inner and outer cylinders.

1 In my improved construction this space is 1 members.

divided into relatively narrow llues by means of longitudinall -disposed'partitions consisting of channel-liars which form'the connection between the two have/'a tendency to prevent the adhesive f ssj from t e extremity which receives the matematerial.- under treatment from clinging to the inner surfaceof the cylinder. The -revolvin structure' is downwardly lnchned which it appertains to make and use the rial from the miXinig-scrubber. As the cylin- ,der revolves there is a constant tendency to cause the material to move forwardly therein, As the material is carried. u wardly on oneside of the c linder and falls ack it will be understood tliat after falling it occupies a position in advance to that'originally occupied when in the lowest part of thecylinder. After the material has traveled through the cylinderr it is taken 'out through the instrumentality of a screw conveyer and carried any desired distancefor further treatment. y

The materialto' be treated in this apparatus is an adhesive tarr substance, a'nd the travelingplows or rab les perform `an im'- portan't function in the treatment of the said material.

Having briefly outlined my im roved construction, Iwill proceed to descri e the same in detail, reference bein made to the accompanying drawings, in w ich is illustrated an embodiment thereof.

In .the drawings, Figure 1y is a plan or top view of the machine. Fig. 2 is a side eleva-V tion, partly in section, along the line 22, Fig.`

1. Fig. 3 is a horizontal section takenon the line 3 3, Fig. 2. Fig. 4'is an end elevation as seen from the front or discharge end of the machine. Figs. 5, 6, and 7 are crosssections taken on the lines 5 5, 6 6,'and 7 7,

respectively, of Fig. 1. Fig. 8 is a fragmentary view showing the front end of themachine in side elevation and on a larger scale. Fig. 9 is a cross-section taken on the line 9 9 Fig. 8, viewed in the direction of the arrows.` Fig. 10 is a top View showing one of the plows or scraper devices with which the sprocketchains are equipped, the same being-shown on a larger scale. Fig. 11 is an elevation of the same viewedl in t e row in Fig. 10. f

The same reference characters mdlcate the same parts in all the views.

Let A designate the inner cylinder, the outer cylinder or mantle ,I and B channel-lrons direction of the ar roc or b ars supporting and stifening the machine and dividing the space between the `cylinder l and mantle into longitudinal ues; f
